now it no longer hardcodes a check for whether the
project name is coreboot. this maintains the same
behaviour but will now work for other multi-tree
projects; in practise, the other multi-tree projects
did not use .gitmodules files anyway, but some of
them used config/submodules/ in our build system.

certain code checks for build.list, to skip it, for
example in items()
we already use config/data/grub to store grub config data
that applied to all trees
create these directories too:
config/data/coreboot
config/data/u-boot
config/data/seabios
move the respective build.list files in here, and also
to config/data/grub
now multi-tree projects contain, per directory, just the
target.cfg file and the patches directory. this is much
cleaner, because some of the logic can be simplified more
Signed-off-by: Leah Rowe <leah@libreboot.org>
instead, check for the presence of target.cfg files
not in config/project/ but config/project/tree/
the way this check is done, it merely returns 1 if
config/project/*/target.cfg is detected, and returns
0 in all other cases, even if config/project/target.cfg
exists
that way, if the maintainer accidentally adds a
target.cfg in the main directory, the given multi-tree
project will not break

this avoids writing the version/versiondate files as root.
this complements the previous fix, that avoided writing those
same files when running the dependencies command.
initial setup of the build system requires root, to run the
dependencies script, but otherwise the build system prevents
running as root for everything else, so we must avoid writing
the version/versiondate files as root.
that same avoidance is necessary when checking whether running
other commands as root; ironically, this check then prevented
running the build system at all!
the bug should be fully fixed now. i found this quite by accident
the other day, when testing something else.
good thing this got fixed because the release!

do it strategically, in just the right place so that the
version and versiondate files aren't written.
otherwise, version/versiondate are written as root and
the build system becomes unusable after that, unless you
reset the file ownerships from root. hardly user-friendly.

already of saying "found", say "already exists"
this means the output of these commands more user
friendly and intuitive:
./update trees -b grub default
./update trees -b coreboot i945
this is just an example. when an ELF file already
exists, the build is skipped even if src isn't downloaded.
this design is intentional, because it means that you can
use previous builds if you want to save time on another.

The xHCI patches were removed because they caused issues
on Sandybridge-based Dell Latitude laptops. See:
https://codeberg.org/libreboot/lbmk/issues/216
The issue was not reported elsewhere, but we still don't
need xHCI support in Canoeboot's GRUB because none of the
available coreboot targets have xHCI support. However, we
may want it in the future and it helps to keep Canoeboot
in sync with Libreboot (this patch is adapted from lbmk).
Each given coreboot target can say which GRUB tree to use
by setting this in target.cfg:
grubtree="xhci"
In the above example, the "xhci" tree would be used. Some
generic GRUB config has been moved to config/data/grub/
and config/grub/ now looks like config/coreboot/ - also,
the grub.cfg file (named "payload" in each tree) is copied
to the GRUB source tree as ".config", then added to GRUB's
memdisk in the same way, as grub.cfg.
Several other design changes had to be made because of this:
* grub.cfg in memdisk no longer automatically jumps to one
in CBFS, but now shows a menuentry for it if available
* Certain commands in script/trees are disabled for GRUB,
such as *config make commands.
* gnulib is now defined in config/submodule/grub/, instead
of config/git/grub - and this mitigates an existing bug
where downloading gnulib first would make grub no longer
possible to download in lbmk.
There is another reason for merging this design change from
lbmk, and that reasoning also applies to lbmk. Specifically:
This change will enable per-board GRUB optimisation in the
future. For example, we hardcode what partitions and LVMs
GRUB scans because * is slow on ICH7-based machines, due
to GRUB's design. On other machines, * is reasonably fast,
for automatically enumerating the list of devices for boot.
Use of * (and other wildcards) could enable our GRUB payload
to automatically boot more distros, with minimal fuss. This
can be done at a later date, in subsequent revisions.

it doesn't build, at present, but isn't used by any
coreboot targets, so the build issue does not come up
during release builds, but i did find it laying around
during my audits.
x86 qemu is on todo for libreboot, on all x86 boards,
but the current config is broken, so: remove it.
it's very much a requirement that anything in lbmk should
work.

it's very unlikely that someone would use this

in practise, the machines we support don't have
the option of including so many disks; 8 seems like
the most reasonable default. additionally, it's
unreasonable to expect *20 partitions*
this hardcoding is done to avoid using *, which is
slow in grub on some machines (the grub kernel always
re-enumerates the devices during every operation,
without caching any of it)
yet, the hardcoding is also slow; balance it a bit
better by searching fewer permutations, but not so few
that it would likely break a lot of setups
Signed-off-by: Leah Rowe <leah@libreboot.org>
we already supported syslinux but not grub
support grub by scanning for the most common paths,
based on the most popular distros
we don't hardcode this with * because it slows down
the boot, and in practise many distros still use the
same grub.cfg location as in BIOS systems (the EFI
one is often just a link to the BIOS one)
Signed-off-by: Leah Rowe <leah@libreboot.org>
this is a relic from the old days when we didn't
automated the grub.cfg logic as much. these days,
the grub.cfg logic is able to boot almost all distros
without any manual intervention or override.
removing these entries will speed up the boot in general
Signed-off-by: Leah Rowe <leah@libreboot.org>
the path "/boot/EFI" is unnecessary because the ESP
is always a FAT32 partition, so we don't need to
scan it as a subdirectory within a subdirectory.
the ESP is always mounted as its own partition,
FAT32, and EFI/ is always at the root of it
Signed-off-by: Leah Rowe <leah@libreboot.org>
the esp is always a fat32 partition so this makes no sensgrub.cfg: don't scan EFI on btrfs subvols

the reason for it is because sometimes the coreboot build
system auto-downloads submodules which we don't want.
however, we now pass UPDATED_SUBMODULES=1 in make, which
disables this behaviour in coreboot's build system.
therefore, remove this unnecessary logic.

i'm merging it into lbmk after this commit. in lbmk, it
will be used for deleting certain files such as u-boot's
strlcat.c. it will not be used in libreboot for deblobbing;
that's what canoeboot is for (deblobbed coreboot distro).

this effectively lets you change the boot order. example:
./build roms -s "nvme ata" t1650_12mb
the above example would set:
grub_scan_disk="nvme ata"
another example:
./build roms -s nvme t1650_12mb
this would set:
grub_scan_disk="nvme"
this overrides what's set in target.cfg for the given
target. useful for quick reconfiguration if building
from source
